SAFETY-LAMP.

Application filed. April 15, 1914.

To all whom it may concern:

Be it known that I, VINOENTE SzAMrnR, a citizen of the United States, and a resident of Terryville, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Safety- Lamps, which improvements are fully set forth in the following specification.

This invention relates to improvements in fluid-burning lamps, and more particularly fluid-burning lamps of that class capable, each of extinguishing its own flame, upon being upset, the same being commonly known as safety lamps; and its object is to provide a lamp, lantern, or the like, of the character above indicated, which shall be simple and comparatively inexpensive as regards its construction; durable, efficient and reliable in practical service; which shall embody features of construction whereby is insured, in the event of the same being upset, particularly upon any object supporting it, the extinction, automatically, of the flame thereof; and which shall possess certain well-defined advantages over prior analogous constructions.

The invention consists in the combinations, details and parts whereby, together with the novel disposition and relative arrangement of said parts, the attainment of the foregoing object is rendered practical, all of which will be hereinafter more specifically referred to and set forth in the appended claims.

The invention is clearly illustrated in the accompanying drawings, wherein similar referencecharacters denote like parts throughout the respective views, and Figure 1 is a fragmentary side elevation, partly in section, of a lamp embodying my said improvements. Fig. 2 is a fragmentary plan view of same, the trip-mechanism housing being removed, and the guard for the tripmechanism 1' aws being partially broken away. Fig. 3 is a view showing in side elevation and detached the wickcasing, certain parts immediately cooperating therewith being shown in vertical section. Fig. i is a view showing in perspective and detached, the trip-mechanism which I purpose making use of, together with certain parts provided for cooperation therewith, the scale being somewhat enlarged.

Having reference to the accompanying drawings, 2 denotes an oil font, as of a lamp, lantern, or the like, the same being Specification of Letters Patent.

Serial No. 831,982.

provided with a burner 2, in the usual manner, said burner fitted with the usual upstanding wick-casing 2", upwardly and downwardly on which rides a flame-extinguisher. This flame-extinguisher comprises, in this instance, a flattened sleeve 3, slidably surrounding the casing 2", and having a downwardly extending arm 3, there being mounted on said sleeve, for a rocking action, as at the opposite points 4:, i, an upwardly extending flap 4:, an elastic element 5, preferably in the form of a leaf-spring and attached to the sleeve 3, as by means of rivets 5, or other suitable fasteners, being provided for controlling the flap aforenamed. The spring 5 bears, at its free end, against the obverse face of the flap 4:, and tends at all times to rock and cause the same to normally span and close the top of the sleeve 3, said flap efiectively assuming this sleeve-closing position when said sleeve duly approaches and reaches its upper limit the casing 3, and being engaged and rocke out of such sleeve-closing position, by the upper edge of the adjacent wall of said casing, when saidsleeve is caused to slide an appropriate distance downwardly along such casing, all as will be readily understood, the construction thus far described being common and well-known in the art.

6 is an operating lever, pivotally disposed as at the point 6, said lever extending from a point exteriorly of the burner 2', freely through the wall of saidburner, by way of a suitable opening 6" formed therein, to a point interiorly of the burner, alongside the wick-casing 2, and into a loose engagement with the arm 3', depending from the sleeve 3, the adjacent end-portion of said lever, freely entering, by preference and in this connection, an eye 7 formed. in the arm 3, as clearly shown in 'Fig. 3.

A. suitable elastic controller, as the extensile spiral spring 7 is interposed between the lever 6, in advance of its fulcrum 6', and any suitable fixed part thereunder, as the base 7 of the burner 2., the tendency of said controller being, .at all times, to thrust upwardly that portion of the lever 6 lying thereover, thus causing, through the medium of the arm 3 and in unison with such upward thrust of said lever, a like upward movement on the part of the sleeve 3, along the casing 2, this movement on the part of said sleeve being sufficient to bring the flap 4 more or less upwardly beyond of travel along ,suitable cl the top edge of the adjacent wall of the easing aforenamed, and so permit said flap to duly rock, under the impulse of its controlling spring 5, into the position the same occupies, and as shown in Fig. 8, for closing the top of the sleeve aforenamed. It will be understood that when the flap 4: occupies its last-named position, as it fully does when sleeve 3 shall have been caused reach its limit of travel upwardly along the casing 2", air-circulation proper for the maintenance of the flame, as

customarily induced at the top of the wick is extinguished.

or steadying the controller aforenamed, when taking the form of a spiral spring, an upstanding pin 8, fixed at its lower end, as to the base 7 of the burner 2, may be disposed to rise axially within the convolutions of said controller, said pin terminating somewhat short of that portion of the lever 6, lying thereover, when the same occupies its lowermost position; and where the burner 2 is provided with an interior crown-plate, as 8", the latter may be suitably cut away, as clearly indicated in Fig. 2, to provide he operating-lever aforenamed is provided, exteriorly of the burner 2, with a finger-piece 9, and also .with a depending stem'9. Said stem supports at its lower end a clevis 9, adapted to swing, as on the being provided, specifically stop, as 14, and

horizontal pivot 10, somewhat upwardly and downwardly, said clevis, in turn, supporting a tongue 9", adapted to swing, as on the normally upright pivot 10, somewhat laterally with respect thereto.

As here shown, the shank of the tongue 9 occupies the opposite, and in this'instance, upward and lower, jawlike members of the clevis 9", tongue 9" at its shank, with a lateral detent 10, which serves to limit its aforenamed, lateral movement, by being caused thereby to impinge against the adjacent portion, as 11, of the body of said clevis. Tongue 9 is further provided with a'detent-shoulde'r 11, here shown as located at one side thereof, and its free-end portion, from and in advance of said detentshoulder, appropriately diminishes, widthwise in this instance, to its tip.

There is attached, as by means of rivets 12,

12, to the burner 2, exteriorly thereof and beneath and in line with-the exposed portion of the lever 6, a horizontalplatform 12, on which isdisposed ajaw13, which jaw works on a pivot 13. Jaw 18 is elastically-com trolled by a suitable spring, as 13", which exerts thereon a force adapted to yieldingly hold thesame suitably in alinement lengthwise with the tongue. 9, said jawbeing earance for that portion of the lever 6 which lies within the burner 2.

normally against a suitable 11 leased, as will be hereinafter explained.

It will be understood that a duplicate of the jaw 13, as 14, arranged for action re versely to the action of the jaw 13, working on a pivot 15, corresponding to 18, and

havin a detent-catch 15, corres ondin t0 1 b b 14: may be availed of when deemed advis-.

able, the tongue 9", in this latter instance, having an additional detent-shoulder 15", corresponding to 11, and likewise an additional detent 16, corresponding to 10; also, the jaws 13, 1% being, under such provision in duplicate of the parts, controlled jointly, as through the medium of the spring 13 aforenamed, and in such a manner that each thereof is urged elastically at all times in the direction of the other, and normally against the stop 14%, situated between them, and said spring, in this latter instance, being contractile and formed from flat material, bowed around said jaws jointly, at the heels thereof, and elastically contracting against the same, respectively, at its opposite ends.

gain, where jaws in duplicate, as above specified, are availed of, tongue 9', under proper manipulation of the lever 6, will move as hereinbefore explained, and to such an extent as will permit the opposite detentcatches 14, 15, to interloekingly engage, respectively, the opposite detent-shoulders 11, 15', of said tongue, with the result, as to restraint on the parts, also as hereinbefore specified, of said jaw or jaws elastically yielding sufficiently, against the controlling spring thereof, to permit the foregoing endwise movement on the part of said tongue. A guard 16, overlying crosswise the jaw or jaws aforenamed, in advance of axes of movement I of when desired, but same isimportant. a

The elastically controlled jaw or jaws parts more or less immediereto, as under a concussion or force gcorrespondingly applied thereto at any point therealong, said annulus being yieldingly suspended, at one side thereof, from the burner 2, as through the medium of a resilient arm 17, suitably connected at its lower end with said annulus, and connected, as by means of a rivet 17 at its upper extremity, with the burner 2, a portion of said arm being returned thereunder, from its upper extremity, for the formation of a counterpoise branch 17", whose lower, free end bears on the oil-font 2, and which materially aids the arm 17 in operating to elastically maintain the annulus 16 in its normal position relatively to said oil-font. The annulus 16 is more or less yieldingly suspended at its side opposite to the arm 17 through the medium of a supplemental, upstanding arm 18, whose upper portion 18, is suitably turned to overlie the jaw or jaws of the trip-mechanism aforenamed, said portion 18, of the arm 18, having a depending stud 18",Whose lower end contacts, though shiftably, with the platform 12", thereby enabling arm 18, with its portion 18, to duly support, as stated, the annulus 16", at the side thereof now under consideration.

ihe trip-mechanism aforenamed, including the portion 18 of the arm 18, is inclosed by a box-like cap or housing 19, which well fits the platform 12", and may be fastened thereon in any convenient and well-known manner. In this connection, however, I purpose providing said housing, whose end-wall adjacent to the arm 18 is duly cut away, as at 19, to provide clearance for the portion 18, with opposite, depending ears, 20, 20, at the lower edges of its opposite side-members, respectively, which ears extend somewhat below said platform, when the housing is in place thereon, said platform being suitably notched or cut away at its opposite side margins to accommodate said ears, an further make use of a pin 20", the latter being inserted through said ears jointly, and in a manner to extend transversely along said platform at the under side thereof, said ears being each duly perforated to this end.

The stud 18 stands normally in such relation to the jaw or jaws of the trip-mechanism aforenamed, as to compel movement thereof, in opposition to the spring which controls the same, as under movement of the annulus 16 radially in any direction out of its normal position, said stud being universally shiftable within proper limits along the platform 12".

The foregoing end may be obtained by providing either or each of the jaws aforenamed with a pocket, as 20", which is measurably occupied at all times by the stud 18", and from which said stud may not escape without exerting on the jaw. or jaws having such pocket a force adapted to compel the same to duly move in the manner above defined.

Where opposite jaws, as 13, 14", are used,

stands shiftably between them, at and measurably within, at its opposite sides, the pocket aforenamed with which each of said jaws is provided, all as clearly indicated in the drawings.

For positively holding theoperating parts of my improved lamp looked, as against the tendency of the spring 7, 1 provide a supplemental lock, which consists of axially alined sections 21, 21, supporting a medial section 21", offset therefrom in parallelism therewith, said sections 21, 21, rotating in opposite bearings 22, 22, arranged posteriorly to the stem 9, and with which platform 12, in this instance is provided, one of the axially alined sections aforenamed, as 21, being provided with a finger-disk, 22.

Then the operating parts of the device are primarily locked against the action of the spring 7, as hereinbefore explained, the same may be positively locked in this condition, by turning the finger-disk 22 properly to cause the medial section 21" to lie against, or in close proximity to, the stem 9, at the back thereof, and this irrespective of any movement imparted to the annulus 16", the function of the latter being thereby annulled; while by further turning said finger-disk properly to cause said medial section to duly recede from said stem, the primarily locked parts may, as by due manipulation of the annulus 16, be freed to respond to the action of spring 7.

If my improved lamp is upset, as on a the stud 18" table or other object supporting it, the parts being primarily locked, as through the medium of the jaw or jaws aforenamed engaging the tongue 9', as hereinbefore explained and wick 8 afiording a flame at its top, annulus 16", by coming in contact with such table or other support, will, under the concussion thus sustained thereby, be moved out of its normal position relatively to the oil-font 2, said operating parts will be released accordingly, and said flame will be promptly extinguished. Or, if the user desires, at any time, to extinguish said flame, through releasement of the operating parts as above defined, it is only needful for him to duly manipulate the annulus 16", accordingly.

It will be seen that my improved safety lamp is well adapted for the purposes for which it is intended, and further that the same may be modified to a considerable extent, particularly as regards the specific character of the trip-mechanism made use of, and as regards various minor details of the general construction, without departing from the scope of the claims hereto appended.
